通过大田试验，研究优化减量施肥对香蕉生长、产量、品质及养分吸收利用的影响，以期为广东雷州半岛香蕉主产区优化施肥提供依据。结果表明：施肥能显著提高香蕉的产量，优化减量施肥香蕉的株高、假茎围、倒三叶叶长优于农民传统施肥。与农民传统施肥(FP)处理相比，高产高效(HH)和改善品质(HQ)处理香蕉产量分别提高9．3%、8．4%，产量有增加趋势。高产高效和改善品质处理能大幅提高香蕉氮、磷、钾肥利用率，提高的百分点分别为3．06~10．39、1．86~5．14、6．07~18．98。在本试验条件下，施肥对香蕉果实品质有一定影响，优化减量施肥能提高香蕉果实品质。因此，优化施肥在我国热带地区具有较大的应用价值。

A field experiment was carried out to investigate the impact of reduced & optimized fertilization on banana (Musa AAA Group Cavendish Williams) growth, yield, quality and nutrient absorption, in order to provide the optimized fertilization for the main banana growing areas in Leizhou Peninsula, Guangdong province. Results showed that the plant height, pseudostem circumference, and the length of leaf Ⅲ of the treatments with reduced & optimized fertilization (HH and HQ) were superior to that of the traditional farmers practices (FP). Compared with FP, the yields of treatments of HH and HQ were increased by 9. 3% and 8. 4% , respectively. And the utilization rate of fertilizer in HH and HQ was significantly im-proved. The N, P2 O5 and K2 O use efficiencies were increased by 3. 06% ~ 10. 39% , 1. 86% ~ 5. 14% , and 6. 07% ~18. 98% , respectively. Under this experimental condition, optimization and reduction of fertilizer application could improve the quality of the banana fruit. Therefore, optimize fertilization should be recommended in tropical regions.
